To all 'whomy t may concern, f

Be it known that fl, Romane J. Koersen, a citizen of the United States, residing at Romulus, in the county ol Pottawatoniie and State of (lklahonia, have invented certain new and useful improvements in Telephone Cnt-Otis, of which the following is a speeilicatioi', reference being had to the aecoinpanving drawings.

i'his invention comprehends certain new and useful improvements in telephone cntolls and has for a special object to .provide e device of this character constructed in sach manner that several persons may use a rural phone line at 'the saine time.

Another object is to provide an apparatus ol this character in wliieh will be employed two line wires attached to each box and to the line Wire on 'the poles at the road, there by making it possible for any Vnumber et conversations to he had over the wire so long as they are not-over the saine parts.

Another object is to provide an automatic telephone eut-oil of this charaete and eonnec-.ted te the line wire on the poles, as above stated, whereby said line Wire becinnee single wires from house to house, instead of continuing as one Wire along,` the entire line.

.Another object is to provide an automatic telephone ent-eil of this character 'which will be of such construction and operation that the part of the line below the box where a long distance message beine` received may be ent ott' and the line thereby made stronger.

Another object is to provide in anton'iatie phone eiitfollf which will be nl' such construe tion' that disturbances (coinnion on rnral lines) may be easily deteeted by cutting oil the phone at various places and thereby linding out which party is bntting in or which vire grounded,

llVitli the above and other objects in vieiv? .my i'nveiition consists in certa in novel constructions, combinations. and arrangigeaients of paatsto be hereinafter niore fully' described, claimed, and illustrated in the aec oinpanying1 drawings, in which,

Figure 1 is a front elevational view ot in v invention applied toa phonebox otordinary construction; and Fig. 2 is a side elevational View thereof. Fig. 3 is a view similar to l 1 .1., showing iny invention positioned inside et 'a phonebox; Fig. el is a detail seetioiial vie-W jon the line 4-4 of Fig. 8; and Fig; is a simil view on the line 5-5 of Fig', 3.

llelferrinio more specilieally to the drawings in which similar retl'irenee characters designate correspondin ij.Y parts throughout the several views, l designates the iront oi' a. telephone box within which is seein-ed a binding' screw Q apen which are, `pivoted the curved cnt-oli levers l and el having their upper ends covered with insulating material7 as shown at 5 and (l respectivelyj said levers being crossed near their upper ends, as will be seen by referring` to the drawings. 'the lower ends 0f the levers 3 and lare directed outwardly in oppoeite' directions, as shown at l and 8 and .normally engaged in the forked upper ents of the pivoted spring nieinbe'rs l and l0, respectively. Vthe box wire ll is secured to the screw The screw 2 also has a spring l2 engaged liln-irearinind to retain the levers il and in raised posif tion9 as will. be later clearly nnderel'owl. The spring; n'ieinbers l) and l0 are pivotecl ngen. the. hinding screws ,lil and ll resjieclivel",y and have their main portions ot'setand their .lower ends ren'iovably engaged beneath the c'i'llset ioitions of the clanii nienibers l5 and lli, said clamp members being; secured to the liront l of the telephone box by means oil' the screws lil" and i8. lo the screi li and '8 are connected 'the inner ends of the anxiliarv line wires l) and Q0 respect ivelif. .vhile the wire 2l is connected to the outer ends el! said ivires lil and Q0. Vlt will therefore be seen that when the .message is lo be sent on over the inain line wire 2l by nav ol 'the auxiliary line wire lll, the upper insiilaled end il el" the lever elis :swung upwardly, thereby turning;i said lever fl upon the screw '12 and disengagingg' the end l there oi troni the ripper forked end of the spline' inenibei l0` tliereb)7 brealiinfy the electrical connections between said end tl of the lever l and the spring; ineniber l0y and preventing; in'essages iii-oni passii'in over the auxiliary line wire '220. lt `will be ini lerstooil that when a message is to be sont in an opposite direction over the main line wire, the lever Il is operated in a siinilar manner to dis-- ,engage the outwardly directed end T' there'- olf from the :spring member l) thereby preventing messages troni travel inal to or ,troia the inain line wire il by way of the anxiliary line wire l5). lt will also be nnderstood that the inner tol-ks of the ripper ends of the spring inenibers il and l0 are bent outwardly, as olea rly shovfn in the drawings in. order that the ends i' and S of the levers CII 3 and e muy be readily engaged with er disengaged from said spring' members 9 and l0.

li; will be seen that. when the receiver hook .is in ils iowermest posit-ion, ii; rests upon the levers 3 and and lnereby prevents npwnrd movement of eitherv lever. lt- Ywill therefore be evideni; that should either o the levers 3 or 4 be in uppermost position during use of the eleplione, said lever will be automatically returned to normal position und forced in engagement Wiib the proper spring member upon downward movelnen' of tbe receiver ilo-ol; 22 caused by the receiver (not slio'ffn) upon replacing or" the receiver thereon.

y'lie lower ends pivoed spring inembere und 1G ere eA iergd end insulated, es slier-:n :.-rb 22 and respeotively, whereby eitlie" of said ends may beengaged and pre.; .d downwardly, lzliereby disengeging the proper Spring member from the elan. i member with which it is normally engaged, xbereby making it possible "Le use the inembersfl :uid AIG ne iemblary eut-Offs in Calling over one end of be line, as will be readily understood.
